RE: Additional test cases for Exclusive XML Canonicalization

This is probably a newbie question. In the examples 2, 3 and 4 there's an
additionalNSPrefixes value next to the xpath expression. Where shd this be
used, and how? Is it supposed to be passed to the XPath evaluator? (I don't
see an API to pass multiple namespace nodes in the Xalan XPath
implementation...)

Joseph,

the XPaths I have provided for my examples are node tests in the sense
of the XPath Transform specified in XMLDSIG. 

So, if you take the well-known ;-) "//. | //@ | //namespace::*" and add
my XPath expression as its node test, you should get the right results.
